Aero regs

As you can see, I'm new to this, so I hope this question is on the right page.

Can anyone tell me if I've missed something or does Article 3.15 (Aerodynamic influence) of the F1 regulations still state, among other things, that "...any specific part of the car... influencing its aerodynamic performance... - must be rigidly secured to the entirely sprung part of the car..."?

If it does, how can Red Bull, and other teams, put all those aerodynamic vanes on their brake ducts? They certainly influence the aerodynamic performance of the car (otherwise why are they there?) and the brake duct is certainly not an "entirely sprung part of the car".

There is another rule that covers this. I think it states that the brake ducts are excluded from the rule and that they can extend a certain distance in from the wheel.

I looked. I see now, thanks Jeremy. I'm sure the ducts never used to be exempt. Looks like a bit of a capitulation there, which is easier than arguing with the teams over what constitutes an air intake and a downforce producing component.
